Abstract (en)
[origin: EP3690186A1] An apparatus and method for designing a blasting sequence for a drilling pattern of a round. The apparatus (11) is configured to assist selecting one or more drill holes (3) for each time delay of the blast. The apparatus calculates burst volume (V<sub>B</sub>) for the selected drill hole set (34) and ensures that previously blasted free volume (V<sub>F</sub>) can receive it when being fired. The apparatus may also take into account burst angles, burst distances and ground vibrations when suggesting the drill hole sets.
